Google does not apply a penalty for ordinary duplication. What happens is consolidation: it picks a canonical version and filters the rest out of results, which can mean the version it chooses is not the one you wanted. Internal duplication typically comes from URL variants, parameters, printer friendly pages, or near identical location pages. External duplication comes from syndicated articles, manufacturer supplied product descriptions and scraped copies. The exception where tone changes is content copied at scale with no added value, which Google's spam policies do treat as a problem.
The practical risk for a service business sits in location pages. Fifty town pages built from the same paragraph with the town name swapped in are near duplicates, and they tend to get filtered down to one or dismissed as thin. Either give each page genuinely local substance, meaning real jobs, photos, reviews and local detail, or build fewer pages. For intentional duplicates like a print version or a tracked URL, set a canonical tag pointing at the original and leave it alone.
